Maintenance Tips
-
Clean condenser coil regularly: Remove dust and grease every 2–3 months to maintain cooling efficiency and reduce compressor strain.
-
Maintain correct temperature (36–38°F): Keep consistent internal temperature for optimal beer storage and draft quality.
-
Ensure proper airflow: Do not block ventilation panels; operate in well-ventilated areas to prevent overheating.
-
Sanitize interior surfaces: Clean stainless steel interior using non-chloride cleaners; avoid abrasive pads or steel brushes to protect finish.
-
Check drain & condensate system: Inspect drain hose and automatic evaporator regularly to prevent water buildup.
-
Inspect refrigeration components: Periodically check compressor and thermostat for stable operation and early fault detection.
-
Door gasket maintenance: Keep seals clean and tight to maintain insulation efficiency and reduce energy loss.
-
Keg handling care: Load and remove kegs carefully to avoid damage to interior floor and slide system.
-
Routine deep cleaning: Fully clean interior periodically for hygiene and long-term performance.
